WT7515
GENERAL DESCRIPTION
The WT7515 provides protection circuits, power good output (PGO), fault protection latch (FPOB),
and a protection detector function (PSONB) control. It can minimize external components of switching
power supply systems in personal computer.
The Over / Under Voltage Detector (OVD / UVD) monitors 3.3V, 5V, 12V input voltage level. The Over
Current Detector (OCD) monitor IS33, IS5, IS12 input current sense. When OVD or UVD or OCD detect
the fault voltage level, the FPOB is latched HIGH and PGO go low. The latch can be reset by PSONB go
HIGH. There is 2.4 ms delay time for PSONB turn off FPOB.
When OVD and UVD and OCD detect the right voltage level, the power good output (PGO) will be
issue.
FEATURES
The Over / Under Voltage Detector (OVD / UVD) monitors 3.3V, 5V, 12V input voltage level.
The Over Current Detector (OCD) monitors IS33, IS5, IS12 input current sense.
Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Output.
75 / 300 ms time delay for UVD.
300 ms time delay for PGO.
38 ms for PSONB input signal De–bounce.
73 us for internal signal De–glitches.
2.4 ms time delay for PSONB turn-off FPOB.
